BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates generally to hot water tank but more particularly to a hot water tank having a removable top lid. The hot water tank comprises a sleeve lining the tank; at least one compartment housed within said sleeve, the compartment having walls for containing water; and a top removable lid; and wherein said sleeve and said compartment are removable from the tank upon removal of said top lid. The sleeve can be sealed or not and has as its particularity that it can be extremely versatile and can have changeable water containers with heating means or not. The sleeve can be adapted to any existing or future water container of any size or model, with or without heating means, and has the possibility of having one or many individual water compartments being exchangeable upon rusting/piercing/breakage, instead of changing the complete tank. The sleeve can also hold the entire contents of the hot water container, if it pierces. The sleeve can also possess a diversified array of sensors (example: water, fire, electricity, etc) and a computer capable of cutting all energy sources, liquid, solids, or gas or other, when, for example, the container leaks. There can also be a valve to empty the contents of the sleeve or the tank when there is a water leak. The computer will let you know of the problem via internet, telephone, insurance, company, police, medical, fire and will shut off the water until help arrives. The water tank according to the present invention can also have a plurality of interconnecting compartments which progressively warm up the water by way of interconnecting pipes. But this concept could be applied to many other things.

Such as any type of liquid or gas contained from leaking, like a double-wall pipeline or even a tank or container in or above ground, lakes river and ocean. The rivers can also be said for the same concept, example: it can also stop the infiltration of gas, liquid or any contaminant from entering inside. Another example of this concept would be double hull boats or even submarines or tanker trucks that upon rupturing the first hull of said boat, submarine and so forth, the inner hull will not be breached and allow anything to enter.

2. Background

Hot water tanks have not evolved much in many years. Whether they are gas, oil or electric, they are basically large reservoirs containing water and means for warming water. In the case of electric water tanks, a lower and an upper element alternate to keep the water evenly warm. An emergency vent on top handles high pressure while a drain at the bottom is used when emptying the tank.

Over the years, a variety of accessories have been developed to complement the features of a hot water tank such as timers to start and stop water heating as an energy saving feature and humidity alarms to detect water leaks and shut off water intake to the tank.

However, there are many improvements to be brought to the hot water tanks which already exist in order to palliate certain inefficiencies with these existing water tanks and therefore, there is a need for an improved hot water tank.

SUMMARY OF THE INVENTION

It is a main object of this invention to provide an improved hot water tank.

In order to do so, the present invention provides a versatile hot water tank comprising:

-   -   a sleeve lining the tank;     -   at least one compartment housed within said sleeve, the         compartment having walls for containing water; and     -   a top removable lid;         and wherein said sleeve and said compartment are removable from         the tank upon removal of said top lid.

But this concept could be applied to many other things. Such as any type of liquid or gas contained from leaking, like a double-wall pipeline or even a tank or container in or above ground, lakes river and ocean. The rivers can also be said for the same concept, example: it can also stop the infiltration of gas, liquid or any contaminant from entering inside. Another example of this concept would be double hull boats or even submarines or tanker trucks that upon rupturing the first hull of said boat, submarine and so forth, the inner hull will not be breached and allow anything to enter.

In a preferred embodiment, the hot water tank includes the whole container can be sealed or not and it has as its particularity that it can be extremely versatile and can have changeable water containers with heating means or not. It may be adapted to any existing or future water container of any size or model, with or without heating means, and having the possibility of having one or many individual water compartments being exchangeable upon rusting/piercing/breakage instead of changing the complete tank.

The sleeve can also hold the entire contents of the container, if the latter pierces. The sleeve can also possess a diversified array of sensors (example: water, fire, electricity, etc) and a computer capable of cutting all energy sources, liquid, solids, or gas or other, when a problem arises, i.e., when, for example, a container leaks. There could also be a valve to empty the contents when there is a water leak. The computer will let you know of the problem via internet, telephone, insurance, company, police, medical, fire and will shut off the water until help arrives. And it can be realized with a plurality of interconnecting compartments which progressively warm up the water by way of interconnecting pipes. As the heat loss from the lower compartments rises, the water container on the top level recuperates the heat loss from the air from the middle and lower level water containers, so as to provide a more economical and ecological hot water tank.

Preferably, the hot water tank includes a plurality of vertically stacked compartments which are lodged within a container, or a sleeve lining the container and providing increased insulation as well as a safety in case of leaks. The container, which can be sealed or not, and if sealed, it can be made airtight or you can replace the air with a gas to increase its insulation properties. The vertically stacked compartments are linked together by interconnecting pipes. Furthermore, as the heat loss from the lower compartments rises, the water compartment on the top level recuperates the heat loss from the middle and lower level water compartments, so as to provide a more economical and ecological hot water tank by heating the water in the upper-most compartment by convection. The tank has a top removable lid which allows for the removal of the sleeve containing the compartments so as to minimize the amount of disposable material (example: heating elements, heating means, water containers, etc) and to facilitate the maintenance of the compartments and/or the sleeve, thus producing a more ecologically friendly hot water tank. Of course, such an advantage as a tank with a top removable lid could be found on a single compartment tank but would lose some of the advantages of a multicompartment tank. Optionally, features such as a humidity detector can warn of a leak and send a signal to electromechanically shut off the water supply to the tank. A timer or computer can also be programmed for partially or totally shut off water heating at selected times. This system can also be used to shut off all kind of energy to the unit, liquids, solids or gas or other, when a problem arises: example, a water container leaks. The computer will let you know of the problem via the internet, and you can program by internet to correct the problem, or by telephone, insurance company, police, medical, fire and will shut off the water until help arrives.

One advantage of a multicompartment tank is that only one compartment needs to be heated to provide hot water on demand during off peak hours, such as nighttime when water from other compartment could be left unheated in order to provide further energy savings while at the same time providing a quicker warmup time since each compartment has its own heating means. Heating means generally refer to means of generating or transferring heat to water such as, but not limited to, electricity, gas, oil, wood, coal, combustible solids, solar, geothermal, nuclear and so forth. All the heating means can be activated at the same time there is constant demand for hot water. However, it is not necessary to have heating means on all the water containers, as the top container recuperates the heat from the lower compartments via the air or the fitted pipes.

The foregoing and other objects, features, and advantages of this invention will become more readily apparent from the following detailed description of a preferred embodiment of the invention with reference to the accompanying drawings, wherein the preferred embodiment of the invention is shown and described, by way of examples such as illustrating 3 compartments whereas as little as two and as many as an infinite number of compartments are defined as “multicompartments”. As will be realized, the invention is capable of other and different embodiments, and its several details are capable of modifications in various obvious respects, all without departing from the spirit invention. Accordingly, the drawings and description are to be regarded as illustrative in nature, and not as restrictive.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIG. 1, there is provided a versatile hot water tank (10). The hot water tank (10) includes a sleeve in which are vertically stacked a plurality of compartments (12,12′,12″). The sleeve is preferably hermetically sealed or air-tight. The sleeve can adapt to any existing or future water container of any size or model, with or without heating means, and having the possibility of having individual or many water compartment being re-changeable upon rusting/piercing/breaking instead of completely changing the tank. The sleeve can also contain or hold the entire contents of the hot water container if it pierces. Preferably also, there is a valve to empty the contents when there is a hot water leak in the sleeve. Furthermore, the sleeve may comprise a diversified array of sensors (for example: water, fire, electricity, etc.) and a computer capable of cutting all energy sources, liquid, solids or gas or other, when a problem arises: for example, when a water container leaks. The computer will let a user know of the problem via internet, and the user is can program by internet to correct the problem, or by telephone, insurance company, police, medical, fire and will shut off the water until help arrives. The compartments are separated from each other. The whole sleeve could be sealed or not, and if sealed, it can be made air-tight and the air inside can be changed to a gas to increase insulation The air-tight space acts to increase the insulation properties of the compartments.

Each compartment may further be provided with heating means (11). The compartments are interconnected by a connecting pipe (16, 16′) of a diameter equivalent to a water inlet pipe (18) or a water outlet pipe (20) so that water can circulate between compartments (12, 12′, 12″) as fast as it can be taken in by the water inlet pipe (18) or taken out by the water outlet pipe (20). It is interesting to note that the connecting pipes (16, 16′) maybe contained within the sleeve (13), or, alternatively, may extend between the sleeve (13) and the tank (10).

The tank (10) is also provided with a top removable lid (15). The lid (15) can be fastened onto the tank (10) by way of any type of mechanical fasteners adequate for securedly attaching the lid (15) in a non permanent manner so as to make it removable. The lid provides increased insulation as well as security in case of leaks. The lid also allows for removal of the sleeve (13) and the compartments (12, 12′, 12″) and the interconnected pipes (16, 16′) with heating means or not so as to minimize the amount of disposal material, (example: heating elements, heating means, water containers, etc.) thus producing a more ecologically friendly hot water tank.

Cold water travels downward from the uppermost compartment (12) where it becomes warm, by way of the connecting pipe (16) to the middle compartment (12′) where it becomes warmer. The water then travels to the lowermost compartment (12″), by way of the connecting pipe (16′) where it is heated to a typical hot water tank temperature. From the lowermost compartment (12″) it exits by the outlet pipe (20) for use.

As shown in FIG. 3, to reduce water's tendency to migrate between compartments (12, 12′, 12″), a heat trap (22) is set on connecting pipes (16, 16′). A heat trap (22) is designd to create an eddy which slows down water circulation, thus slowing down water migration. It consists of two ends (23, 23′) interfacing with a pipe; in this case, the pipe is the connecting pipe (16, 16′) which is sectioned off to allow insertion of the heat trap (22).The heat trap (22) is generally formed by two substantially parallel pipe segments (25, 25′) and joining segments (27, 27′).

When a user uses hot water, the water will be taken from the lowermost compartment (12″) which will require water from the middle compartment (12′) to replenish it. Therefore, water in the connecting pipes (16, 16′) will travel from a higher compartment, either the uppermost compartment (12) or the middle compartment (12′), towards a lower compartment, either the middle compartment (12′) or the lowermost compartment (12″) respectively. However, when no one uses the water, warmer water will tend to migrate, by way of the connecting pipes (16, 16′), from the lower compartments, where it is warmer, to higher compartments, where it is cooler. In order to slow down the migration, a heat trap (22) is placed within the path of the connecting pipe (16, 16′). Because of the two paths water can take in the pipe segments (25, 25′), along with the direction as indicated by the arrows, an eddy is created by conflicting tendencies of water having different temperatures. For example, warm water does not want to travel downwards as it is forced to do in the pipe segment (25) but it wants to go up as it does in the pipe segment (25′), which creates an eddy which in turn tends to draw cooler water rather than letting warmer water migrate towards cooler water. There is still transfer of heat but it is slowed down.

As such, one advantage of a multicompartment tank is that only one compartment needs to be heated to provide hot water on demand during off peak hours, such as nighttime when water from other compartment could be left unheated in order to provide further energy savings while at the same time providing a quicker warmup time since each compartment has its own heating means. Heating means generally refer to means of generating or transferring heat to water such as, but not limited to, electricity, gas, oil, wood, coal, combustible solids, solar, geothermal, nuclear and so forth. All the heating means can be activated at the same time there is constant demand for hot water. However, it is not necessary to have heating means on all the water containers, as the top container recuperates the heat from the lower compartments via the air-tight space surrounding the compartments or the fitted pipes.

The heat trap (22) can be used on standard hot water tanks as well as any type of plumbing where heat transfer needs to be slowed down and can therefore have applications well beyond the application discussed in this instant invention.

Another preferred embodiment of the invention is shown in FIG. 2. The hot water tank (10) can include the heat traps (22) but where the connecting pipes (16, 16′) run inside the sleeve (13) instead of outside of it as per the embodiment shown in FIG. 1.

But this concept could be applied to many other things. Such as any type of liquid or gas contained from leaking, like a double-wall pipeline or even a tank or container in or above ground, lakes river and ocean. The rivers can also be said for the same concept, example: it can also stop the infiltration of gas, liquid or any contaminant from entering inside. Another example of this concept would be double hull boats or even submarines or tanker trucks that upon rupturing the first hull of said boat, submarine and so forth, the inner hull will not be breached and allow anything to enter.
